You are welcome.  I will double check with newlib folks why my patches did not get
incorporated (maybe they were, after 5.0?).

Well, that is sort of embarasing.  The reason is that we still have only one
preferences file and, for people that work on more than one project, making
this a default is very inconvenient (it takes you by surprise).

We are planning on having project preferences, but the details are still being
discussed.

I had an idea recently to make options that are valid while you are working
in the same directory.  Insight would ask you to confirm if you want to keep
those preferences if you start it from a different directory.  I haven't even
posted this idea yet (so you are hearing it first hand).

But a solution will come.

That is what the list is for.  There are several people working with Angel 
targets so maybe someone knoes the answer.

Note that sometimes people are busy, travelling, on vacation, or no one knows.
But it always worth a try.

Toronto is 3 hours ahead of Silicon Valley.  And I keep asking our engineers
in Germany what is the time difference for them and I keep forgetting!
And there is all these changes to save daylight...
